Conversions seem to be in vogue these days, judging by the recent “Circumcise Me” and now “Hebrew School Dropout,” Dave Konig’s account of how he went from Judaism to Catholicism and back again.

But while the comedian’s a genial figure, his one-man show seems more of an excuse for name dropping than a resonant examination of its topic.

“All my life I’ve been a mediocre Jew,” he concedes at the top of the show, before describing how he was driven to convert after marrying an Irish-Catholic.

He took to his new faith with such purpose that he got a gig hosting a Catholic-oriented talk show on satellite radio. His choice of guests — Jewish comedians, most of them — didn’t exactly endear him to the church.

While some good one-liners dot the show’s 70 minutes — “It’s like Vegas!” he exclaims, admiring the church pageantry — Konig squanders his premise’s potential with a scattershot series of anecdotes.

Among the topics touched on are entertaining 9/11 rescue workers and his encounters with such figures as Marisa Tomei, Adam Sandler, Deepak Chopra and flamboyant exercise guru Richard Simmons.

The proceedings are casual to the extreme. Performing on a set containing a stool and, for some reason even he can’t explain, a potted plant, Konig frequently tries to engage his audience members personally, at one point leaping off the stage to hand someone an autographed book of comic essays written by his wife.

But despite its performer’s ingratiating manner, “Hebrew School Dropout,” with such tired tropes as a comparison between Christmas and Hanukkah, lacks bite. At least it’s aptly housed — in the historic Actors Temple Theatre, whose former congregants, we learn, included Milton Berle, Jack Benny and two of the Three Stooges. Exactly which two, even Konig doesn’t know.
